摘　　要：双有源桥(DAB)变换器三重移相(TPS)调制方法需要预先求取系统的调制参数,难以建立并求解精确的全局效率最优目标函数。本文提出了一种基于粒子群优化(PSO)算法实现DAB变换器全局效率最优的寻优方法以解决上述问题,使变换器能以高效率在整个工作范围内运行,并保持较低的无功环流和电流峰值。仿真与实验结果都验证了所提方法的正确性与可行性。The triple phase shift(TPS)modulation method of double active bridge(DAB)converter needs to get the modulation parameters of the system in advance,so it is difficult to establish and solve the accurate global efficiency optimal objective function. An optimization method based on particle swarm optimization(PSO)algorithm is proposed to achieve the global efficiency optimization of DAB converter to solve the above problems,so that the converter can operate efficiently in the full load range,maintain low reactive power and peak current value. Simulation and experimental results verify the correctness and feasibility of the proposed method.
